Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To provide the residual fuel quantity detecting device of a vehicle which solves the defficiency that rapid decrease of a residual quantity is observed in a displaying device. SOLUTION: After the starting time of measurement by a residual quantity sensor (point C), even if it becomes possible for the residual quantity sensor to detect, a residual quantity detected by the signal from the residual quantity sensor is not immediately displayed on a displaying device. Instead, a residual quantity is calculated by subtracting a consumed quantity, which is detected from the input of a signal from the injector, from residual quantity set by detecting the consumed quantity from the input of the signal from the injector. The residual quantity calculated above is compared with a quantity detected by the residual quantity sensor.  When the value of the former quantity is larger than that of the latter, the value of the former quantity calculated above multiplied by a coefficient K (<1.00) is obtained as the residual quantity and is displayed on the displaying device (range X).
